Abstract

Transapical implantation of artificial chordae using the NeoChord system (NeoChord Inc, Minneapolis, MN) is an emerging beating-heart technique for correction of mitral regurgitation (MR) through a minimally invasive left minithoracotomy. The purpose of the study was to describe the anesthetic management and procedural success of patients undergoing this procedure. All patients (n = 76) who underwent mitral valve repair with the NeoChord system in our institution from December 2011 to December 2016 were included in this observational prospective study. Balanced anesthesia with a combination of fentanyl, propofol, and sevoflurane was used in all patients. Each patient's core temperature was maintained at >36°C whenever possible. Two- and 3-dimensional transesophageal echocardiography was used in all patients to navigate the device to the posterior mitral valve leaflet (68 of 76 patients), anterior mitral valve leaflet (3 of 76 patients), or both leaflets (5 of 76 patients). After effective leaflet capture, the artificial chordae were deployed. Position and function of the artificial chordae were assessed by evaluating the degree of MR when the neochordae were tensed. After surgery, all patients were transferred to the intensive ...Continue Reading
